One end of a metal rod is in contact with a thermal reservoir at 745 K, and the other end is in contact with a thermal reservoir at 105 K. The rod and reservoirs make up a closed system. If 7030 J are conducted from one end of the rod to the other uniformly (no change in temperature along the rod) ...
a) ... what is the change in entropy of the 745-K reservoir?
b) ... what is the change in entropy of the 105-K reservoir?
c) ... what is the change in entropy of the rod?
d) ... what is the change in entropy of the system?
